Work? If not, can you export your sashelp.vtable to csv and post it? Never come across this problem before, could it be that the library is assigned and then the underlying folder is deleted or something like, could there betwo entries in the?

Re: SASHELP.VTABLE Error: Libname doesn´t exist

Yes, can't see anything there. Do a filter on all sashelp - not just where the problem occurs - of all views. Basically try to narrow down where the problem occurs - it maybe a special character in a file, it may be a connection to database etc. So run a select on everything in sashelp. Then exclude views, if that works we can look at just views, so retrestrict to that, narrow it down each run.
